Definitions
- the present invention relates to a shielding means for a needle of a container-needle assembly
- a shielding means for a needle of a container-needle assembly comprising a container having an elongate body, a needle and connecting parts for connecting the container releasably with the needle, said shielding means comprising two coaxial tubular bodies, an inner and an outer body, which are made to telescope in relation to each other.
- the outer tubular body is adapted to at least partially receive the body of the container, and the inner tubular body is adapted to be displaced from a retracted position in which the needle is exposed, to an advanced position in which the needle is surrounded by the inner tubular body.
- the invention further relates to a container-needle assembly
- a container-needle assembly comprising a container having an elongate body, a needle and connecting parts connecting the container releasably with the needle and comprising a shielding means having two coaxial tubular bodies, an inner and an outer body, which are made to telescope in relation to each other.
- the outer tubular body is adapted to at least partially receive the body of the container, and the inner tubular body is adapted to be displaced from a retracted position, in which the needle is exposed, to an advanced position, in which the needle is surrounded by the inner tubular body.
- U.S. Pat. No. 4,923,447 (Morgan) and U.S. Pat. No. 5 318 547 (Altshur) disclose shielding means comprising two coaxial tubular bodies, an inner and an outer body, which are made to telescope in relation to each other, the outer of which is adapted to receive the container of a container-needle assembly and to be secured to the far end of said container relative to the needle.
- An operation projection at the inner tubular body extends through a longitudinal slot of the outer tubular body and may be operated by a user in order to displace the inner tubular body to an advanced position in which it surrounds and shields the needle.
- Said known shielding means are thus connected with the container-needle assembly at the far end of the container relative to the needle.
- Said known shielding means are thus connected with the container-needle assembly at the far end of the container relative to the needle.
- Such a removal is not possible in connection with the known shielding means.
- connection means is preferably adapted for connecting said outer tubular body with said hub part.
- connection means comprises preferably an annular shoulder and means for engaging with and retaining the hub part when positioned at said shoulder.
- the connecting parts between the container and the needle may comprise a single part, e.g. a rubber membrane closing the container at the needle end of the container.
- the needle is preferably designed as a double-ended needle comprising a point in both ends, the needle being retained by the connection means, and the membrane is pierced by the needle so that the needle points are located on each side of the membrane when the container-needle assembly and the shielding means are assembled.
- connection means is preferably connected with one end of the outer tubular body through a narrow intermediate piece extending through a longitudinal slot of the inner tubular body.
- the object is also achieved by means of a container-needle assembly of the type mentioned in the opening part which is characteristic of connection means for connecting said outer tubular body with the needle without connecting to the container.
- a container-needle assembly may be ready-made and be sterilized by the manufacturer and delivered to the user ready for use.
- FIG. 1 shows a section through the outer tubular body of the shielding means
- FIG. 2 shows a section through the inner tubular body
- FIG. 3 shows a section through the outer and inner tubular body when assembled, as shown by the line III—III of FIG. 6,
- FIG. 4 shows a partial section along the line IV—IV of FIG. 3,
- FIG. 5 shows a partial section along the line V—V of FIG. 3,
- FIG. 6 shows the assembled outer and inner tubular body seen from the left side of FIG. 3,
- FIG. 7 shows a partially sectional view of the assembled outer and inner tubular body provided with a capped needle
- FIG. 8 shows a blood sampler
- FIG. 9 shows a view corresponding to FIG. 7, but having the blood sampler of FIG. 8 in position
- FIGS. 10-12 show a sequence of the handling of the device in connection with sampling
- FIG. 13 shows a view indicating the handling of the shielding means
- FIG. 14 shows an exploded perspective view of a container-needle assembly
- FIG. 15 shows an enlarged section of FIG. 14 showing one end of the outer tubular body
- FIG. 16 shows a perspective section through the same end of the outer tubular body as shown by the arrows XVI—XVI of FIG. 6 .
- the shielding means shown in FIGS. 1-6 and 14 comprises an outer tubular body 1 , one end of which is provided with a finger tab 2 and the other end of which is provided with a connection means 3 for a needle.
- the connection means 3 is connected with the remaining part of the outer tubular body 1 through a narrow intermediate piece 4 .
- the shielding means further comprises an inner tubular body 5 , one end of which is provided with an operation button 6 , connected with the inner tubular body 5 through a second intermediate piece 7 .
- the two tubular bodies 1 and 5 are each provided with a longitudinal slot 8 and 9 , respectively, extending through said entire tubular body, except for a small piece 10 and 11 , respectively, in one end.
- the intermediate piece 4 extends through the slot 9 and the intermediate piece 7 extends through the slot 8 as appears from FIGS. 4 and 5.
- the intermediate piece 4 (see FIG. 5) has an essentially rectangular cross section whereas the intermediate piece 7 (see FIG. 4) has a wedge-shaped cross section, and the slot 8 is provided with indentations 12 thus establishing a stop for the intermediate piece 7 at each end of the slot 8 . It is thereby achieved that the position of the inner tubular body 5 relative to the outer tubular body 1 may be retained, both in the retracted position shown in FIG.
- connection means 3 which is shown most clearly in FIGS. 15 and 16, is in the embodiment shown designed to receive a common, commercially available needle 13 provided with a conical hub 14 with a hub collar 15 (see FIGS. 7 and 9 - 12 ).
- the-connection means 3 is shaped like a cup with a hole 25 in the bottom and an internal opening whose profile 16 corresponds to the circumference of the hub collar 15 .
- the connection means 3 is provided with two (FIGS. 14, 15 and 16 ) or three (FIGS. 1-6) inwardly extending, resilient tabs 17 adapted to provide a snap lock engagement with the hub collar 15 as appears from FIGS. 7 and 9 - 12 .
- the hub collar 15 is thereby retained between a shoulder 18 constituted by the other part of the bottom of the cup and the tabs 17 .
- FIG. 7 shows the shielding means of FIG. 3 provided with a needle which again is provided with a protection cap 19 , thereby revealing only the hub 14 of the needle.
- the protection cap 19 shown is a common, commercially available cap with a collar 20 preventing the protection cap from being moved through the hole 25 of the connection means 3 , and accordingly the needle must be mounted from the left side of the figures, but in connection with another needle with a protection cap designed differently it may be possible to mount the needle from the right side of the figures, i.e. the entire needle with the protection cap is moved through the tubular bodies and secured in the connection means 3 which in that case is adapted to receive the needle from that side.
- FIG. 8 shows the container part of a container-needle assembly
- said container part may as an example be a special blood sampler having a container 21 and a connecting piece 22
- FIG. 9 shows the sampler introduced into the shielding means and the connecting piece 22 received in the hub 14 of the needle 13 in order to connect the needle and sampler.
- FIG. 10 shows the container-needle assembly of FIG. 9 upon blood sampling.
- the protection cap 19 is removed from the needle, and to avoid the user of the sampler getting in contact with the needle point 13 , the inner tubular body 5 is advanced to the position shown in FIG. 11 by means of the operation button 6 . This is done by one single motion of hand as illustrated in FIG. 13 .
- the sampler may be removed from the needle 13 and from the shielding means as shown in FIG. 12 .
- the profile 16 of the opening of the connection means 3 corresponds to the profile of the hub collar 15 , which preferably is not rotationally symmetric, as it is thus possible to turn the sampler relative to the needle 13 and thus facilitating the release of the sampler. Due to the pointed shape of the second intermediate piece 7 , the inner tubular body 5 is retained with a relatively strong resistance against movement to the right in the FIGS.
- the shielding means is preferably made of a polymeric material of some rigidity and preferably of a transparent material so that it is possible to observe the container when used.
- the rigidity (elastic modulus) of the material should preferably be in the range of 200 N/mm 2 to 5000 N/mm 2 .
- Examples of applicable materials are polyethylene, polypropylene, polymethylpentene, polystyrene, modified compounds of styrene-polymers and polystyrene, polycarbonate, polymethylmethacrylate (acrylics), polyamide, polyvinylchloride, polyethylenterephthalate (polyester), including modified polyesters.
- the outer tubular body 1 is made of styrene/acrylonitrile copolymer, SAN, (BASF, Luran 368R) and the inner tubular body 5 is made of styrene/butadiene copolymer, S/B, (BASF Styrolux 637D).
- a manufacturer of the shielding means described above may choose among several ways of delivering the shielding means to the user.
- One way is to deliver an assembled, sterilized unit comprising a container mounted with a needle onto which the shielding means is mounted.
- the shielding means and the needle need not be separable from each other, but may as an example be welded together by ultrasonic welding.
- Other ways are to deliver the shielding means alone or together with the container, but without the needle.
- the connection means must be adapted to commonly available needles and the user himself has to mount the shielding means onto the needle and connect the needle with the container.
- the use of the shielding means will now be explained in connection with arterial blood sampling by means of the blood sampler 21 which in the first case mentioned above is delivered having the needle 13 and the shielding means mounted.
- the user e.g. a laboratory assistant
- the packaging contains the sampler provided with a needle of the correct size with a protection cap as well as the shielding means and a tipcap for the sampler.
- the user also brings along latex gloves, a swap, gauze and plaster.
- the method is as follows:
- the user puts on the latex gloves.
- the selected puncture site is washed with alcohol by means of the swap.
- the sterile packaging is opened aseptically.
- the plunger of the sampler 21 is set to the sample volume required.
- the protection cap 19 is removed from the needle 13 .
- the artery is located using the index finger/middle finger of one hand.
- the puncture is performed by the other hand.
- it is important that the hub part 14 of the needle is visible in order to assess the first flash of the arterial blood.
- the filling of the sampler 21 is monitored.
- the needle is withdrawn and the puncture site is compressed with one hand.
- sampler 21 is turned to mix anticoagulant present in the blood sample taken.
- the sampler is turned/withdrawn from the needle and the shielding means which along with the used needle is discarded with other sharp waste.
- the tipcap is mounted onto the sampler which is carried to an analyzer.
- the tipcap is then removed, a few drops of blood are spilled whereupon the blood is injected into the analyzer.
- the used sampler is discarded along with other sharp waste and/or blood-contaminated waste.
- the “sampler” need not be a plunger sampler, but any sampling container comprising an elongate body whose one end is connected releasably with a needle may be used.
- the shielding means may also be applied in connection with other container-needle assemblies than for blood sampling, e.g. for injections.
